Achillea Plant Named `FLORACHRE1&#39;

ABSTRACT

A new and distinct cultivar of  Achillea  plant named ‘FLORACHRE1’, characterized by its dark red-colored inflorescences, medium green-colored foliage, low growth vigor and compact-upright growth habit, is disclosed.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/763,295 filed Jun. 8, 2018.

Latin name of genus and species of plant claimed: Achillea millefolium.

Variety denomination: ‘FLORACHRE1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Achillea plant botanically known as Achillea millefolium and hereinafter referred to by the cultivar name ‘FLORACHRE1’.

The new cultivar originated in a controlled breeding program in Quedlinburg, Germany during May 2012. The objective of the breeding program was the development of Achillea cultivars having attractive flower coloration and a compact growth habit suitable for container plantings.

The new Achillea cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is the proprietary Achillea millefollum breeding selection coded 10213-4, not patented, characterized by its medium orange-rose colored inflorescences, medium green-colored foliage, and vigorous, upright growth habit. The male (pollen) parent of the new cultivar is from is unknown. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during July 2013 in a controlled environment in Quedlinburg, Germany.

Asexual reproduction of the new cultivar by terminal stem cuttings since July 2013 in Quedlinburg, Germany, Hendrik-Ido-Ambacht, The Netherlands, and Elburn, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘FLORACHRE1’ as a new and distinct cultivar of Achillea plant:

-   -   1. Dark red-colored inflorescences;     -   2. Medium green-colored foliage;     -   3. Low growth vigor; and     -   4. Compact-upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a different inflorescence color and in having a more compact growth habit.

Of the many commercially available Achillea cultivars, the most similar in comparison to the new cultivar is ‘Flowerburst Red Shades’, not patented. However, in comparison, plants of the new cultivar differ from plants of ‘Flowerburst Red Shades’ in at least the following characteristics:

-   -   1. Plants of the new cultivar are more compact, as measured by         plant height, than plants of ‘Flowerburst Red Shades’; and     -   2. Plants of the new cultivar have a uniform dark-red         inflorescence color unlike plants of ‘Flowerburst Red Shades’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘FLORACHRE1’. The plants were grown in 13 cm containers for 12 weeks outdoors in Hendrik-Ido-Ambacht, The Netherlands.

FIG. 1 illustrates a side view of the overall growth and flowering habit of ‘FLORACHRE1’.

FIG. 2 illustrates a close-up view of an individual inflorescence of ‘FLORACHRE1’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2015 edition, except where general color terms of ordinary significance are used. The color values were determined in July 2019 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown as three plants per pot in one-gallon containers for approximately 17 weeks in a greenhouse in Elburn, Ill. Greenhouse temperatures were maintained at approximately 60° F. to 65° F. (15.5° C. to 18.3° C.) during the day and approximately 55° F. to 60° F. (12.7° C. to 15.5° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
